Mini-Gigabit Interface Connector
(Mini-GBIC) Installation Note
You can add and remove mini-GBICs from your Extreme Networks switch without powering
off the system. There are two types of mini-GBIC interfaces: the LX mini-GBIC, which conforms
to the 1000BASE-LX standard, and the SX mini-GBIC, which conforms to the 1000BASE-SX
standard. The mini-GBIC connector, which is shown in Figure 1, is the same for both types of
mini-GBIC interfaces.

Mini-GBICs are a Class 1 laser device. Use only Extreme-approved devices.
Remove the LC fiber-optic connector from the mini-GBIC prior to removing the
mini-GBIC from the port.
Mini-GBICs can emit invisible laser radiation. Avoid direct eye exposure to beam.
If you see an amber blinking mini-GBIC port status LED on your Extreme Networks
switch or you receive an error message when you install a non-Extreme-supported
mini-GBIC, you do not have an Extreme-supported mini-GBIC installed in your switch. To
correct this problem, make sure you install an Extreme-supported mini-GBIC into the port
on the switch.
To remove the mini-GBIC connector, gently push in the plastic tab at the bottom of the
connector and pull the mini-GBIC out of the port on the switch.
To insert a mini-GBIC connector:
1 Holding the mini-GBIC by its sides, insert the mini-GBIC into the port on the switch.
2 Slide the mini-GBIC into the port, until you hear it click.

Mini-Gigabit Interface Connector (Mini-GBIC) Installation Note 2
LX Mini-GBIC Specifications
Table 1 describes the specifications for the LX mini-GBIC interface.
Total optical system budget for the LX mini-GBIC is 13.5 dBm. Measure cable plant losses with
a 1310 nm light source and verify this to be within budget. When calculating the maximum
distance attainable using optical cable with a specified loss per kilometer (for example 0.25
dB/km) Extreme Networks recommends that 3 dBm of the total budget be reserved for losses
induced by cable splices/connectors and operating margin. Thus, 10.5 dBm remains available
for cable induced attenuation. There is no minimum attenuation or minimum cable length
restriction.
SX Mini-GBIC Specifications
Table 2 describes the specifications for the SX mini-GBIC interface.
Total optical system budget for the SX mini-GBIC is 11.5 dBm. Extreme Networks recommends
that 3 dBm of the total budget be reserved for losses induced by cable splices/connectors and
operating margin. While 8.5 dBm remains available for cable induced attenuation, the
1000Base-SX standard specifies supported distances of 275 meters over 62.5 micron multimode
fiber and 550 meters over 50 micron multimode fiber. There is no minimum attenuation or
minimum cable length restriction.
